To all whom it may concern:

Be it known that I, EDWARD T. BETKER,

a citizen of the United States, residing at Kansas City, in the county 'of Jacksonand State of Missouri, have invented certain new and useful Improvements in Alternate Rotary Driving Mechanism,fof which the following is a specification. j

My invention relates tonew and useful improvements in driving mechanism for imartin alternate rotar motion to an ma t7 chine to whichmy mechanism may be appl ed, and while my mventlon 1s capableof more or less general use, it is particularly useful'in driving cleaning and extracting.

machines. r v

One important feature resides in the shifting mechanism which controls the alternattional view of my driving gear on line II of Fig.4. Fig.2 is a vertical cross sectional View, with some of the parts removed, on line IIII of Fig. 1 and looking in the direction of arrow a. i Fig. a section on] line II-II, of Fig. 1, looking in the (urea tion of 6. Fig.4 is a plan View of the driving gear.

In carrying out the invention,I employ a main shaft 1, which is constantly-driven .in one directioneltherby hand or power as de, sired, a handle Qbemg used when the mechanism is to be drivenby hand, and apulley 3 being used when the mechanism is to'b power driven. Shaft 1 isjournaled in bear-f ings 4 and 5 ofa frame 6,'and isheld from lateral movement by collars 7 and 8 and a' cog wheel 9. The collars 'Z. andS abut the bearings 4 and 5 and thecog wheel 9 is keyed or otherwiserigidly'mounted upon the shaft 1 and abuts the oppositeside of the bearing 5 from that engaged by the col- Applicationfiled April 17, 1915.

The counter shaft 11' isheld from longitudinal movement by the v cog wheel 10 abutting one side'of the bearing' 13 and a collar 14' engaging the opposite sideof the bearing '13, said collar-14being fixedlymounted upon the counter shaftll by'any suitablemeans, such as a pin 15.

one side of a sleeve 27, securedto the frame 6 by any suitable means, such as a set screw 28'. 5 The shifting lever 24 is provided'at its 7 ends with laterally projectingstuds 29, and

30, which project into the peripheral grooves 31 and 32 of clutch members 33 and 34, slidably mounted upon shafts 1 and.11, but made to rotate therewith through the intermediacy of feathers 35 and 36, respectively.

The clutch members 33 and 34 are adapted to' -dr ive companion clutch members 37-.and;

38, loosely-mounted upon the shafts 1 -and li and provided with small integ'ralcog wheels .39 and40, respectively, whichf are in con stant engagement with a large cog wheel'41 mounted upon a power transmlssion shaft 42, journaled in a bearing 43, on the frame 6.

The clutch members 37 and 33 are yieldingly -held against collars 44 and 45 fixed to the shafts 1 and 11,- by coil springs46 and 47 interposed betweensaid clutch members 37 and 38 and the adjacent cog wheels. 9 and 10,

respectively. The shaft 42 may be connectedto thegearing. of a cleaning andextractmg machinefor any other mechanism to which it is desired teimpart an alternating rotary motion.

'In practice the shaft 1 is constantly driven, I

in one direction and int'urn constantly drives the shaft 11 in an opposite direction through the intermediaey of the cog wheels 9 and 10-. I the lever 22 at intervals through the intermediacy of the Worm 16, the Worm Wheel, 17,

and thus imparts alternating rotary motion to the transmission shaft 42 through the intermedi'acy'of the cog wheels 39, 4:0 and 41.

By yieldingly' mounting the clutch members 37"and 88 all danger of breaking their teeth is avoided, because when their respective clutch members 83 and 3a are forced forwar-di m engagement thereby by the shifting lever 2+}, the springs 16 and- 47 yield until the clutchteeth reach the engaging po sitions, when the clutch members 37 and 38 areiminediately forced into engaging positions bysaid springs 4:6 and '47.

From the 'foregoing description it is a parent that I have'produced an alternating rotary driving Qniechanism which is positive and reliable in its'action', and While I have shoivn'and described the preferred form of my invention, I reserve the right to make such-changes in the construction, combinati'omand arrangementof'parts as properly fall Within the spirit and scope of the claims. 7
